A History of Connection

Our Story

Zayo’s journey has been guided by an aspirational vision for connectivity. Our founders were veterans of the companies that constructed the earliest backbone of the Internet. They understood that truly putting “the world” on the World Wide Web would require connections, lots of them.

We are connectors

In 2007 they formed Zayo with a vision of accumulating, connecting and optimizing an unparalleled global network of networks. With 47 successful acquisitions to date, we not only know what to buy and where, we know how to connect and harmonize.

We connected the world

As a global internet backbone company, Zayo is the leading independent provider of light-speed data transmission infrastructure, with dense, high-quality networks connecting every major market in North America and many in Western Europe. Through partnerships with complementary network providers, we provide our customers with global reach that takes them nearly anywhere they need to be.

We connected the dots

We knew that data capture and processing technologies would evolve rapidly and demand for data transmission would multiply exponentially along with it. So we connected great people to create bespoke Zayo networking solutions for customers, extending their network reach as their businesses evolved.

We connect what's next

New technologies, more data, & changing consumer expectations mean an even greater reliance on the connections that we make possible. And we’re expanding all the time – providing new mission-critical routes for customers, more density, additional diversity and reduced latency. We’re laying the foundation for our 5G future, artificial intelligence, the metaverse and beyond.
